Following high-level criticisms of the Hinkley C nuclear plant from HSBC and the Chancellor's father in law, EDF, the company in line to build the power station, is fighting back hard, writes Oliver Tickell. But it could all be too late to rescue the doomed project.
Solar panels made using perovskite technology pay back the energy used to make them ten times faster than those using silicon. In time, this could lead to similar falls in price.
With the US, China, Germany and other countries firmly fixing their aim on a low carbon, renewable energy future, the UK government has chosen precisely the opposite track, write Noam Bergman, Lee Stapleton & Mari Martiskainen. Its mission to destroy wind and solar power, undercut energy efficiency and boost nuclear power and fracking threatens serious, lasting damage.
There's one big thing that Britain's biggest banks could do to reclaim their grievously impaired reputations, writes Greig Aitken: commit to stop investing in coal projects. As well as reducing climate change and local environmental impacts, it would also 'de-risk' their balance sheets as the global tide, from the US to China, turns against the dirty, carbon-heavy fuel.
The UK government has timed its attacks on renewable energy to perfection, writes Alasdair Cameron. Public 'consultations' on proposals to cut away support for wind and solar are running over the holidays - and many of those affected don't even know about it. It's time for us all to stand up for the green economy and make our voices heard!
Never mind government inaction (or worse) on climate change, writes Assaad W Razzouk. Solar power costs just keep on falling, and it's already providing the lowest cost electricity across much of the world. With $7 trillion of investment piling into the sector, the momentum is now unstoppable.
The wind is a force of nature over which only someone with extraordinary delusions of grandeur can truly claim ownership, writes Adam Ramsay. But to prevent that, we must assert our belief that wind, sun and other drivers of our renewable future are a common heritage for us all to benefit from.
Batteries may have a big role in balancing future power grids, writes Sean Meyn, enabling more wind and solar generation. But until we go beyond 50% renewables, we don't need them. Instead we can adjust the demand of power hungry appliances to what's available every moment of the day.
Engineers in Norway aim to put their mighty hydroelectric dams to a new purpose, writes Paul Brown - as giant batteries to store up surplus power from wind and sun across Europe, and put it back in the grid when generation falls off or demand is strong.
Are you suffering from cognitive dissonance? You should be, writes Oliver Tickell. After the most ferocious attack a UK government has ever mounted on the environment, David Cameron just claimed that his is the 'greenest government ever', as Amber Rudd proclaims her commitment to climate action. What's going on?
Shale gas company Cuadrilla will appeal Lancashire's decision to refuse permission to frack, write Kyla Mandel & Ben Lucas. The planning battle will last well into 2016, as campaigners prepare to fight all the way.
The damage caused by fracking to people, communities and the wider environment will be put under the legal spotlight in public hearings in the US and the UK, write Damien Short & Tom Kerns. While the 'ruling' that emerges will be non-binding, it will provide an authoritative, expert dossier of fact and argument for real legal actions to follow.
Perplexed by today's sharp cuts in solar power and other attacks on renewable energy in the UK? Don't be, writes Oliver Tickell. Really, it all makes perfect sense. You just have to understand their real purpose: to keep your energy bills high, along with power company profits. And never mind the 'green crap'!
The UK government has announced massive cuts in support for solar roofs and farms that appear designed to undermine investor confidence just as the technology is on track to be subsidy-free by 2020.
The anti-fracking movement scored a great victory when Lancashire councillors refused planning permission for two fracking wells, writes Damien Short. But dig deeper and the triumph was all the greater, as it overcame not just Cuadrilla, but a morass of pro-fracking bias and legal and scientific misrepresentation from those meant to be providing impartial advice.
